I heard a friend introduce this product, saying that it works well and won't rebound after eating it. I bought a box the other day and only ate it for three days. After eating, I feel my heart beating faster from time to time, dizzy and hot all day. I don't feel hungry and I don't want to eat anything. I weighed it today, and I lost 4 pounds in three days. The effect is really good. But I'm still worried that the side effects will damage my health. I decided not to eat.
